One of the biggest threats posed by quantum computers is their ability to break public-key cryptography. This encryption system underpins the security of blockchain networks like Bitcoin and Ethereum. In this system, two keys are used: a public key that is accessible to everyone and a private key that is only held by the owner. The security of this system relies on mathematical problems like the discrete logarithm problem, which are impossible or extremely time-consuming to solve with classical computers.
